Just like grinding foreign workers, they have been negotiating for three days and three nights, and everyone is red-eyed and begins to overdraw. This is the first face-to-face negotiation with aliens, and people can't help but be excited.

Even Zhang Yuan, a bystander, smelled a kind of gunsmoke on the battlefield.

Until the afternoon of the fourth day, the scientists in charge of related science and technology were already a little unable to support it, and they were crazy to inject themselves with stimulants!

At this time, the first transaction was finally preliminarily completed.

The two sides exchanged some knowledge of each other's generative cognition of intelligence, brain perception science, and some biomimicry knowledge, and they were quite satisfied with each other's gains......

Finally, the Toth civilization said: "The respected new human civilization, limited by the perceived limitations of my civilization, and the conventional interstellar cultural etiquette is not applicable to my civilization, I hope you can understand." ”

"No problem, of course it's no problem! I hope that after this transaction, we can both achieve something and forge a deep friendship. ”

The conventional interstellar civilization etiquette is to turn on the camera, at least to make the image spokesperson of the entire civilization, so that the other party knows what the counterparty looks like.

But this Toth civilization did not have eyes, yes, they did not have eyes, they could not see any pictures, they usually used ultrasound and magnetic field perception instead of traditional vision. This civilization doesn't even have the relevant optical camera technology, so naturally there is no need to turn on the camera.

It is precisely because this interstellar civilization is so peculiar that human beings have gained some knowledge of magnetic field perception in this transaction.

Of course, the more knowledge about intelligence in this kind, the better, and human beings have only completed the first step of brain transformation, and there is a second and third step to follow......

Brain perception is a very important part of intelligence.

There is no way to drive with red-green color blindness, and the learning speed of blind or deaf-mute people is not as fast as that of normal humans, and the importance of perception is self-evident in the field of scientific research.

There are some people who have very good auditory memory and some spatial thinking skills. In fact, in general, their outstanding talent in a certain aspect is that they are much stronger than ordinary people in the establishment of different perception systems.

But is human perception perfect? Of course not, for example, the electromagnetic field, which is a real substance, is completely imperceptible to human beings, so many people have difficulty understanding the forces associated with electromagnetic fields.

Ultrasound, infrasound, infrared, ultraviolet rays, humans cannot perceive ......

These strange papers on "magnetic field cognition" are unbelievable to human beings, and they cannot be ignored because they involve the real field of intelligence.

Since this is a private transaction, there is no way to guarantee the correctness of this knowledge, so many researchers immediately began to discern the authenticity of the paper after the transaction was completed.

Of course, under normal circumstances, this kind of small transaction does not need to do too much, otherwise it will have a bad reputation in this trading market and nothing can be done.

"This member of the Thoth civilization is really very peculiar!" One of the experts glanced at the articles a few times and exclaimed with a hint of strangeness.

"The world they perceive is completely different from that of human beings. The human eye sees pictures and strange lines...... Is it magnetic field sensible......"

"Therefore, the direction in which the Toth civilization studies nature is very different from ours. They can feel the electric current directly, or in other words, the electric and magnetic fields generated by the electric current! The birth of modern power technology is a very simple and easy thing for them, which is incredible! ”

The world perceived by each intelligent creature is different, and generally speaking, the perception ability of living beings is mainly based on photons, sound waves, and heat radiation.

But the individuals of the Toth civilization can actually feel the magnetic field!

Until now, people still have no way to understand what it is like to "feel a magnetic field".

Zhang Yuan frowned, and imagined as much as possible the feeling of being surrounded by magnetic lines, but in the end, he still couldn't imagine it.

Real perception is inevitably not comparable to some magnetic inductance lines, and the series of chain reactions brought about are even more difficult to predict.

He had a flash of inspiration and suddenly said: "Pigeons can use the earth's magnetic field to distinguish directions, maybe pigeons have the primary ability to feel the magnetic field...... But no one can describe what it feels like for a pigeon to distinguish a magnetic field. ”

"If human beings can also feel the magnetic field, it will inevitably promote the research of some cutting-edge science. But how can we add another kind of perception to the human brain? ”

It's so hard! No matter how smart you are, you can't describe the feeling that humans themselves lack.

After discussing for a while, everyone shifted the topic to the technology tree of the Torth civilization, the electromagnetic industrial system of this civilization is far stronger than the normal third-level civilization, but other technologies are not very good, especially optical technology, it is simply plummeting, not like a third-level civilization......

In physics, there is a saying that if a scientist habitually works with his neck crooked, that is, everything he sees is at an angle of about 30 degrees from a normal person, the whole world is tilted to him.

In his field of vision, the apple will fall to the ground at an angle of 60 degrees, and the way humans walk is also tilted, everything is oblique.

So, will the physics studied by this scientist with a tilted neck be different from that of a normal person?

On the other hand, if a scientist studies natural phenomena in front of a mirror. So is the physics in the mirror the same as the physical laws of reality?

In the same way, the perception of one life is different from that of another. What you see is a photon, but what I see is a magnetic field, so will the two sides have different understandings of nature?

"At least judging from the current performance, the development of the tech tree will be very different, and the level of difficulty will also be very different."

Again, this is a big issue.

"Even, because the brain of the Toth civilization is different from other civilizations, the difficulty of self-improvement has increased a lot, and it can be regarded as a gain and a loss."

After such a lively discussion, many scientific research workers really couldn't stay sleepy, so they were busy and went to sleep.

Humans are not steel after all, and after such a long negotiation, they are really a bit overdrawn. Doping can't be fought anymore, otherwise it will have to happen.

A third of them were still on duty, checking for new knowledge sent by the other party.

Zhang Yuan had just woken up from a sweet dream, energetically analyzing a patent drawing on the electromagnetic industry, and he imported these data into the computer to analyze the feasibility of simulating these patents, and whether there was anything worth learning from......

While simulating, I talked to my peers about what I had gained this time.

"This DB-SDQ grating is quite interesting, it can efficiently receive light quanta and distribute them."

"How does it compare to our technology?"

"It's hard to say, we have to actually apply it to know, and for a while we can only know through the computer that it really works."
